More about 'One week flat'

Lactobacillus acidophilus Rosell-52: acidophilus is a natural resident of the intestinal microflora; this strain of acidophilus from OptiBac Probiotics has been shown to survive gastric acidity and biliary salts, and to reach the intestines without damage.

Bifidobacterium bifidum Rosell-71: In-vitro tests suggest that this strain flourishes well with Fructooligosaccharides.

Lactobacillus casei Rosell-215 is of an extensively studied species naturally residing in the intestinal flora; this strain from OptiBac Probiotics has been researched in its ability to resist gastric acidity and bile salts in order to reach your small and large intestines alive.

Lactococcus lactis Rosell-1058 is extracted from the kefir culture, and has been scientifically proven to reach the gut alive.

Fructooligosaccharide fibres (FOS) predominantly settle in the large intestine where they may act as a food source to stimulate the growth of your body's natural bacteria.

This 7 day course is ideal for those looking for a short term, high quality natural bacteria supplement.

Background information

Unlike similar foods and supplements containing live cultures, 'One week flat' is free from added sugars and does not contain gluten, and may therefore be suitable for those with bloating. Abdominal or stomach bloating is thought to be associated with food intolerances, constipation, over-eating, PMS or intestinal gas; leaving the abdomen feeling uncomfortable, full and tight. If you have poor digestion, waste materials and the gases they produce can remain in the gut for long periods of time, often at high temperatures and pressures. This causes bloating and stretching of the gut walls beyond their comfortable limits. An imbalance of bacteria in the gut may result in poor digestive health, bloating, production of smelly and uncomfortable gases, and sluggish bowels. This imbalance is known as dysbiosis.

Healthcare professionals can see Scientific Research on live cultures and bloating.

Please note: As of May 2014, this product has a new name ('One week flat') in the EU. The ingredients remain the same.

Directions

As a natural food supplement 'One week flat' can be given to adults and children from 4 years old & up, with the following recommendations: Take one sachet daily with breakfast for a 7 day course, or as professionally directed.

We highly recommend you take 'One week flat' for 7 consecutive days. Most customers take this course once a month, but it can taken as often as desired. For more information see our FAQ: How often should I take OptiBac 'One week flat'?

For best results:

  • I have suffered with IBS for just over 8 years. Earlier this year i got introduced to the FODMAP diet, this is a diet regime for those with IBS to figure out what has a reaction. please take a look if you do it has been an incredible change for me. The bloating though does still ocur and as many IBS sufferers know by the end of the day we can be 2 sizes bigger than in the morning. OptiBac Probiotics have now combated my bloating so i no longer have that uncomfortable bloat. I have even had a reaction from a meal the night before, taking probiotic one week flat sachet and a little later i lost the bloat! Now a daily routine, never felt better.

  • Response from OptiBac Probiotics

    Dear Linda, I’m sorry to hear that the product was not helpful for your IBS symptoms. IBS is different for everyone, and sometimes what works for some doesn’t work for others. We’d also always underline that different probiotics will work in different ways, so it might be a case of trial and error whilst you find one for you. If you'd like to talk to our team of nutritional therapists about this further please don't hesitate to email us on [email protected] and we’d be more than happy to help / see if we can advise anything different. Best regards, Emeka.
